Day 1: On the very first day of life, a newborn’s stomach is as small as a hazelnut. This is the reason why baby needs to be fed often in order to feel full. Newborns should be fed between 8-12 times in 24h.
Day 2: Your baby might have dropped a little weight after birth (which is absolutely normal), but his stomach size is already growing! By the second day, it should be the size of a cherry and still need to feed every 1 to 3 hours.
Day 3: Your baby’s stomach is now about the size of a walnut. Your little one should be producing around 3 wet diapers.
Day 7: By the end of the first week of his life, his stomach has grown so much and is already the size of an apricot! Baby should be putting on some weight and produce around 6 wet diapers a day.
